WEBVTT

00:00:02.800 --> 00:00:09.200
I can yes

00:00:09.200 --> 00:00:13.120
okay um yeah so I'm uh zachary canfer

00:00:13.120 --> 00:00:14.920
let's go to the

00:00:14.920 --> 00:00:17.520
questions uh the first question uh why

00:00:17.520 --> 00:00:19.119
do we go top to bottom for time

00:00:19.119 --> 00:00:19.840
progression

00:00:19.840 --> 00:00:23.920
uh and left to right uh for low to high

00:00:23.920 --> 00:00:27.279
interesting I think uh so the initial

00:00:27.279 --> 00:00:30.000
uh thing I was copying that initial app

00:00:30.000 --> 00:00:31.599
work this way

00:00:31.599 --> 00:00:35.280
um and

00:00:35.280 --> 00:00:36.960
yeah I mean certainly traditional music

00:00:36.960 --> 00:00:38.960
you know on a staff uh

00:00:38.960 --> 00:00:43.040
does go left to right uh like this

00:00:43.040 --> 00:00:46.000
um I mean going top to bottom does make

00:00:46.000 --> 00:00:47.440
it easier to add more beats without

00:00:47.440 --> 00:00:48.960
having to wrap but certainly that could

00:00:48.960 --> 00:00:49.920
be managed

00:00:49.920 --> 00:00:52.239
um yeah I I had not really thought about

00:00:52.239 --> 00:00:53.760
it but it is definitely something worth

00:00:53.760 --> 00:00:55.199
looking into

00:00:55.199 --> 00:01:02.480
uh yeah you are now unmuted

00:01:02.480 --> 00:01:05.680
ah good point thank you let me go ahead

00:01:05.680 --> 00:01:06.960
and do that

00:01:06.960 --> 00:01:14.240
uh the entire screen

00:01:14.240 --> 00:01:16.880
okay so the screen share should be

00:01:16.880 --> 00:01:18.320
starting

00:01:18.320 --> 00:01:21.439
there we go cool all right uh

00:01:21.439 --> 00:01:24.880
two will be placed on the song um not

00:01:24.880 --> 00:01:26.640
now I can I can make some recordings of

00:01:26.640 --> 00:01:28.080
it or certainly you can try it

00:01:28.080 --> 00:01:30.720
um I couldn't quite get the the

00:01:30.720 --> 00:01:33.119
microphone and the webcam and everything

00:01:33.119 --> 00:01:37.040
to work with the sound playing now um so

00:01:37.040 --> 00:01:40.079
uh I can record some also please uh

00:01:40.079 --> 00:01:43.520
I put a link at the uh here in the uh

00:01:43.520 --> 00:01:46.640
etherpad https://zck.me/emacsconf2020 

00:01:46.640 --> 00:01:48.479
where you can go and get the source

00:01:48.479 --> 00:01:49.920
and you can try it yourself uh there's

00:01:49.920 --> 00:01:51.920
no dependencies needed so it's just all

00:01:51.920 --> 00:01:54.560
in Emacs um so please you know try it

00:01:54.560 --> 00:01:57.040
yourself

00:01:57.040 --> 00:02:00.079
any chance for an Emacs tracker or mod

00:02:00.079 --> 00:02:01.040
player

00:02:01.040 --> 00:02:03.680
um I don't really know what a mod player

00:02:03.680 --> 00:02:04.479
or tracker

00:02:04.479 --> 00:02:08.000
are but I mean I'm sure

00:02:08.000 --> 00:02:09.679
that would be cool uh maybe there's one

00:02:09.679 --> 00:02:11.599
on now but I don't know uh

00:02:11.599 --> 00:02:13.920
my musical background so I've played

00:02:13.920 --> 00:02:15.200
various instruments since about the

00:02:15.200 --> 00:02:15.840
third grade

00:02:15.840 --> 00:02:18.160
uh started recorder uh play cello I play

00:02:18.160 --> 00:02:19.520
guitar now

00:02:19.520 --> 00:02:22.560
um but yeah so just kind of random

00:02:22.560 --> 00:02:23.680
instruments and

00:02:23.680 --> 00:02:26.959
uh yeah I guess kind of some of those

00:02:26.959 --> 00:02:27.280
things

00:02:27.280 --> 00:02:30.480
influence how I think about music um

00:02:30.480 --> 00:02:33.519
uh yeah um

00:02:33.519 --> 00:02:35.360
are there any open source musical

00:02:35.360 --> 00:02:36.640
management sample libraries that could

00:02:36.640 --> 00:02:37.840
be used

00:02:37.840 --> 00:02:41.200
um good question I'm sure there are um I

00:02:41.200 --> 00:02:42.400
don't know any that integrate really

00:02:42.400 --> 00:02:43.360
well with Emacs

00:02:43.360 --> 00:02:44.560
one of the cool things that I liked

00:02:44.560 --> 00:02:45.680
about this is that there are no

00:02:45.680 --> 00:02:47.440
dependencies

00:02:47.440 --> 00:02:49.360
you know you don't need any external

00:02:49.360 --> 00:02:50.800
program to

00:02:50.800 --> 00:02:53.040
uh generate the music I mean it it does

00:02:53.040 --> 00:02:54.160
shell out to

00:02:54.160 --> 00:02:57.280
to play um but that

00:02:57.280 --> 00:02:58.640
should be able to be done on any

00:02:58.640 --> 00:02:59.840
operating system as always you have

00:02:59.840 --> 00:03:03.519
something that can play wav files

00:03:03.519 --> 00:03:05.599
um but yeah it is interesting to kind of

00:03:05.599 --> 00:03:06.879
try the different

00:03:06.879 --> 00:03:10.000
uh different sounds and different

00:03:10.000 --> 00:03:12.239
tones uh that you could get with

00:03:12.239 --> 00:03:14.400
different instruments

00:03:14.400 --> 00:03:16.959
have I written any actual songs um

00:03:16.959 --> 00:03:17.599
nothing

00:03:17.599 --> 00:03:21.040
super uh

00:03:21.040 --> 00:03:23.680
uh well put together just I kind of just

00:03:23.680 --> 00:03:25.519
been playing around with this

00:03:25.519 --> 00:03:27.440
it's kind of I making this was one of

00:03:27.440 --> 00:03:29.040
those things where like once I made it I

00:03:29.040 --> 00:03:30.080
was like okay

00:03:30.080 --> 00:03:31.280
now I can play with it and I did a

00:03:31.280 --> 00:03:32.720
little bit and was like I don't know if

00:03:32.720 --> 00:03:33.920
I feel like it right now

00:03:33.920 --> 00:03:37.280
you know which I've I've found that to

00:03:37.280 --> 00:03:38.720
be the case with some things that I've

00:03:38.720 --> 00:03:39.599
implemented

00:03:39.599 --> 00:03:41.360
in Emacs where it's I make it and then

00:03:41.360 --> 00:03:43.519
it's the kind of some of the desire to

00:03:43.519 --> 00:03:44.480
use it all the time

00:03:44.480 --> 00:03:46.879
goes away but I'm sure I'll circle back

00:03:46.879 --> 00:03:47.760
around

00:03:47.760 --> 00:03:51.040
at some point especially kind of maybe

00:03:51.040 --> 00:03:52.400
once I add in different tones or

00:03:52.400 --> 00:03:54.640
something

00:03:54.640 --> 00:03:56.400
I guess a similar question for

00:03:56.400 --> 00:03:57.840
pre-recorded sounds yeah I mean

00:03:57.840 --> 00:04:01.120
if it's part of what I did what I wrote

00:04:01.120 --> 00:04:02.080
was a

00:04:02.080 --> 00:04:04.720
wave generation library so if you kind

00:04:04.720 --> 00:04:06.720
of have the data

00:04:06.720 --> 00:04:08.400
you could use those and like chop them

00:04:08.400 --> 00:04:10.159
up and take certain lengths of them

00:04:10.159 --> 00:04:13.360
and make a wav file so it's not plug and

00:04:13.360 --> 00:04:14.959
play right now but you could certainly

00:04:14.959 --> 00:04:19.120
add those notes uh to do it

00:04:19.120 --> 00:04:21.040
um any knitting midi mapping

00:04:21.040 --> 00:04:22.720
possibilities um

00:04:22.720 --> 00:04:24.560
I haven't looked into it but I'm sure

00:04:24.560 --> 00:04:26.160
you definitely could output to midi

00:04:26.160 --> 00:04:28.800
um which is another benefit of having

00:04:28.800 --> 00:04:30.400
that multiple layers with the top layer

00:04:30.400 --> 00:04:31.520
is just like

00:04:31.520 --> 00:04:33.360
um you know if the root note is this

00:04:33.360 --> 00:04:35.120
we're just two semitones up or seven

00:04:35.120 --> 00:04:36.560
semitones up or whatever it is

00:04:36.560 --> 00:04:38.160
uh it should be relatively simple to

00:04:38.160 --> 00:04:40.720
kind of switch out that layer underneath

00:04:40.720 --> 00:04:44.479
uh from wave to midi or other things

00:04:44.479 --> 00:04:45.759
what were some of the challenges with

00:04:45.759 --> 00:04:47.520
writing a special mode for Emacs

00:04:47.520 --> 00:04:49.759
uh interested in getting into this not

00:04:49.759 --> 00:04:51.040
sure where to start

00:04:51.040 --> 00:04:54.960
um there uh yeah it so

00:04:54.960 --> 00:04:57.120
this isn't the first mode I've written

00:04:57.120 --> 00:04:58.320
um so that's right

00:04:58.320 --> 00:05:01.759
certainly that helps um I actually

00:05:01.759 --> 00:05:05.600
um I have a video that we recorded it

00:05:05.600 --> 00:05:08.240
as part of Emacs nyc on making a major

00:05:08.240 --> 00:05:09.039
mode

00:05:09.039 --> 00:05:10.720
that's basically like starts from

00:05:10.720 --> 00:05:12.639
nothing and kind of builds up to

00:05:12.639 --> 00:05:15.680
an implementation of tic-tac-toe um

00:05:15.680 --> 00:05:17.039
but so it kind of goes into printing

00:05:17.039 --> 00:05:19.600
things out and buttons and making the

00:05:19.600 --> 00:05:21.280
mode

00:05:21.280 --> 00:05:22.800
I mean one of the best parts about Emacs

00:05:22.800 --> 00:05:24.560
is because it's so

00:05:24.560 --> 00:05:26.479
uh configurable and so introspectible

00:05:26.479 --> 00:05:28.479
you can start pretty simply

00:05:28.479 --> 00:05:30.320
and just kind of asking max about things

00:05:30.320 --> 00:05:32.320
and then make one little

00:05:32.320 --> 00:05:34.960
change um it's really it's not that bad

00:05:34.960 --> 00:05:36.479
so uh

00:05:36.479 --> 00:05:39.039
I'll try to throw a link up on that uh

00:05:39.039 --> 00:05:40.560
on on that page I put up or

00:05:40.560 --> 00:05:42.000
please email me for whoever asked this

00:05:42.000 --> 00:05:44.479
question uh to get a link to that video

00:05:44.479 --> 00:05:46.240
um or just look at look at the source

00:05:46.240 --> 00:05:47.919
code of this or any other major mode

00:05:47.919 --> 00:05:50.479
um it it's pretty ems breaks it makes it

00:05:50.479 --> 00:05:52.880
pretty easy to extend uh

00:05:52.880 --> 00:05:56.479
major modes and I think that's that's

00:05:56.479 --> 00:05:57.600
the last question

00:05:57.600 --> 00:06:00.240
in the ether pad so uh thanks so much

00:06:00.240 --> 00:06:02.479
everybody for coming

00:06:02.479 --> 00:06:06.720
you are now unmuted uh thank you so much

00:06:06.720 --> 00:06:09.039
to curry for your awesome talk

00:06:09.039 --> 00:06:12.960
and for doing live questions

00:06:12.960 --> 00:06:19.840
thank you thank you cheers
